Visual flow indicator or sight glass for utility industry must be highly reliable. Absolute uptime is a necessity for power utilities. LJ Star has a wide selection.
Sight glasses and flow indicators are important components in utility applications such as waste water treatment, allowing operators to observe processes inside of pipes and vessels. L.J. Star products are installed on dryers, agitators, purification systems, separators, evaporators, ASME pressure vessels, furnaces and feed tanks.
A flow indicator mounted on a pipe lets operators see flow between processes, while a sight glass assembly installed on a tank lets operators view the material in the tank. A level indicator lets operators view the water level in a vessel.
Sight glasses are often used on boilers in utility industries such as coal-fired power plants. L.J. Star can tailor its extensive array of products for application-specific requirements such as meeting boiler codes. For utility and other higher pressure, high temperature applications, L.J. Star’s METAGLAS® fused-glass sight glasses provide extreme strength and long service. METAGLAS is a special formulation of borosilicate glass that is more resistant than ordinary glass to thermal shock and overpressure.
Other L.J. Star products used in utility industry applications include gauge glass, explosion proof lights (ex-lights), non-ex lights and camera systems.
